    Mitral valve prolapse (MVP) is common, but this study found no link between echocardiographic MVP evidence and patient symptoms or disability. Other factors likely cause functional impairment in suspected MVP cases.

    Area of Science:

    • Cardiology
    • Echocardiography
    • Clinical Medicine

    Background:

    • Mitral valve prolapse (MVP) is frequently suspected as a cause of various symptoms and complications.
    • The direct relationship between echocardiographic findings of MVP and patient-reported outcomes remains unclear.

    Purpose of the Study:

    • To investigate whether symptoms and functional impairment in patients with suspected mitral valve prolapse are directly associated with echocardiographic evidence of MVP.
    • To differentiate the impact of MVP itself from other potential causes of patient-reported issues.

    Main Methods:

    • A cohort of 274 outpatients with suspected MVP underwent echocardiography.
    • 158 patients were followed up for 14 to 36 months with interviews to assess symptoms, disability, and healthcare utilization.

    Main Results:

    • No significant association was found between echocardiographic evidence of MVP and reported symptoms, disability, or healthcare utilization.
    • Patient demographics (age, sex) and initial symptoms were similar between groups with and without MVP.
    • A high rate of dysfunction was observed, but it did not correlate with the presence of MVP on echocardiography.

    Conclusions:

    • Echocardiographic diagnosis of mitral valve prolapse does not appear to be directly related to the symptoms and functional impairment experienced by patients.
    • The functional impairment observed in patients suspected of MVP may stem from factors other than the valve condition itself.
    • Further research is needed to identify the underlying causes of symptoms in patients with suspected MVP.
